This invention relates to a radiant heater which embodies improved meansfor heating the air of a room, hall, etc.

An important object is to provide a more cheaply manufactured sheet ironconstruction of the furnace wall so arranged to co operate with theupper ends of the radiants as to removably support the latter in ancilicient manner.

A further object is to simplify and cheapen the interior construction ofa heater by the provision of a novel metal member which is adapted bothto support the heating elements and to form portions of the walls of theheater casing.

Other objects and advantages may hereinafter appear.

Referring to the accompanying drawingswhich illustrate a preferredembodiment of the invention.

Figure 1 is a front view of a portable heater embodying the invention.

Figure 2 is a vertical section on line 22 of Figure 1.

Figure 3 is a horizontal section on line 3--3 of Figure 1.

Referring in detail to the drawings, the upright casing 5 is providedwith an open face 6 just behind which is located the upright heatingelements 7. Said heating ele ments are heated by a series of burnerelements 8 of any desired construction located therebeneath, as wellshown in Figure 2, the lower portion of the casing being provided with aburner chamber 9 having a front wall 10 provided with cold air intakes11 and 11 at its front and bottom sides respectively. At the top of thecasing is provided a heated air chamber .12, there being located betweensaid chambers 9 and 12 a jacket 13 which partially encloses the seriesof heating elements 7 and which has a rear wall 14 in spaced relation tothe back wall 15 of the furnace casing, thereby forming an upright fine16, and side lines 16 which lead from the burner chamber 9 to the topchamber 12.

Referring in detail to the construction of the acket 13, said jacket bypreference and as shown, consists of an upward prolongation of the sheetmetal wall 10 of the heater casing, said wall 10 having a rearwardextension 18 adjacent thereto. The part 18 at its rear edge joins therear wall 14- of said jacket. The top of the jacket has a for wardlydirected portion 19 which terminates in a channelled flange 20 that isfitted over the upwardly extending top flanges 2.1 of the heatingelements 7.

Each of the heating elements 7 is provided with a top wall 22 which isinclined downwardly and rearwardly in spaced relation to the top wall.19 of the jacket 13, and the aforcmentioi'ied back wall 1 1 of saidjacket is spaced rearwardly of the heating elements 7, thus providing aheat radiating chamber 2-5 between said heating elements and said wall14.

The top chamber12 of the heater is provided in its top wall 12" with anupwardly and forwardly directed apertured portion 24 to direct the airforwardly and upwardly into the room, it being understood that thefurnace will usually be placed with its back 15 near one of the walls ofthe room.

The bottom 10 of the heater is shown formed as a rearward continuationof the front wall 10 and with air intake openings 11 passingtherethrough. Said bottom is shown having a flange 10" for attachment tothe back of the furnace by means of rivets 10. The member which formsthe top and back of the furnace may consist either of cast iron or ofsheet iron. Sheet metal mom bers 11 and 14 may support the cross wall 18which supports the heating elements 7. Cross wall 18 is formed of aseparate piece of metal in order to provide for expansion andcontraction thereof, independently of the adjacent members of theheater.

In operation, heated air is radiated horizontally into the room from theupright heating elements 7 located at the front side of the heater andforming the front wall of the chamber 23; while at the same time upwardly and forwardly directed currents of heated air a re escaping into theroom through the apertured top portion 24 which is located above theheating elements 7. Owing to the currents of heated air being deliveredinto the room from these two sources and in two general directions ashas been explained, there is created within the room an eiiicientcirculation of heated air by passing air through intakes 11 and 11 intochamber 9, thence through the lines 16 and 16 into chamber 12, andthrough said apertured portion 24 as indicated in the annexed drawing.

I claim In a radiant heater, an upright casing having a front wall whichis provided with a downwardly directed lip Which forms the upper marginof the opening for the heater proper, a heating element within saidcasing nel portion Whichfits around the rear, top

and front of said upright flange and which abuts against the innersurface of said. ]i p of the casing, said channel portion consisting ofangular bends of the sheet metal in which it is located.

In testimony whereof I affix my si 'nature.
